sPooL-HEAD FASTENING.

SPECIFICATION forming part of Letters Patent No. 580,297, dated April 6,1897.

Application led January 20, 1897- Serial No. 619,894. (No model.)

To all whom t may concern:

Be it known that I, MARSHALL TILLorsoN, of Vassalborough, in the countyof Kennebeo and State of Main e,have invented an Improvement inSpool-Head Fastenings, of which the following description, vinconnection With the accompanying drawings, is a specification, likeletters on the drawings representing like parts.

This invention has for its object to provide a spool with anovelfastening device by which to attach its head to its body very securely,so that there will be no liability of the head becoming loose on thebody or the journals outside the head becoming loose.

In accordance with my invention I attach the heads to the body by meansof lockingdogs, which, when in place, constitute a U shaped loop, whichmay be in two pieces orone piece, it presenting a portion which isextended diametrically across the axis of the body of the beam, leavingtwo substantiallyparallel arms which extend toward the end of the beam,said ends passing through the head and through the usual metal platelying outside the beam-head and beyond which the usual journal of thebeam extends, said arms being securely fastened in or to said plate.

Figure l shows a face or end view of a spool having its head attached inaccordance with my invention. Fig. 2 is a longitudinal section 011 theline Fig. l. Figs. 3, 4, and 5 show modifications of my invention, andFig. 6 is a detail of Fig. 5. j

In accordance With my invention the body A of the spool and the head bare and may be all as usual. The journal O is rounded Where it isexposed outside of the head, and its opposite end is forged to a squareor other irregular shape in cross-section, so that when driven intoaround hole made in the end of the beam the journal will be securelyfixed in place beyond any possibility of its being turned. The metallicWasher O', applied to the outer side of the head on the said journal,may be of usual shape.

In Figs. l and 2 I provide the body A, as shown,

with a transverse bore or hole ct, in

which I enter a portion of the U -shaped locking-dog or loop-likefastening device D, the

dog or loop represented in said iigures being shown as composed of twoparts, each having a head and bent near its inner end, as at d2, each ofsaid ends being preferably beveled and provided With a hook or lockingdevice d.

To secure the heads on the body, Figs. l and 2, I first put thelocking-dogs or loops through the holes in the plate O and then throughenlarged holes b made in the head, bringing the points of the bent armsd2 of the dogs or loops opposite the outer ends of the bore or hole c,as shown by dotted lines in Fig. 2, the said hole being located at sucha distance from the end of the beam that as the bent ends enter the saidbore or hole, they being driven therein by blows of a ham mer or otherdevice, the said dogs or loops act to draw the head rmly upon or againstthe end of the body, the bore or hole being commonly called a draw-bore.

The bent ends cl2 of the dog or loop are driven into the bore or holeuntil the hooked ends pass each other and lock together, and thereafterit Will be practicallyimpossible to remove the heads or for the head inany inanner to become loose.

In the modification, Fig. 3, I have omitted the hooks at the ends of thebent portions d'2.

In Fig. 4 I have shown a loop (marked E) as made in one piece of wire,the wire forinin g the loop being irst inserted through the bore or holea when straight and being then bent into the U form, after which thehead and the journal-plate will be applied to the ends of the twoparallel arms of the loop, and

-the said ends will thereafter be headed or upset in said holes at theouter portion of the plate. In Fig. 5 I have shown a similarloop, whichI have designated F, its ends being provided With screw-threads, uponWhich I have applied nuts e, one of the said nuts being shown detachedin Fig. G, and these nuts, when screwed down snugly in place, may belocked against accidental rotation by driving a nail through the hole cin the nut, the hole entering the head l).

The spool herein described may be used to hold yarns for spinningtelegraphic or other wire, or for any other purpose required of suchspool.

IOO

Having fully described my invention, what I claim, and desire to secureby LettersPatent, is-

1. A spool composed of a body having a transverse bore or hole, a headand a metallic plate applied thereto outside the head, the said head andplate being connected to the body by a U-shaped dog or loop havingportions extended transversely through the bore or hole in the body, theheads on the parallel arms of the dog or loop engaging the plate outsidethe head at the end of the body, substantially as described.

2. A spool-bodyhaving a transverse bore or hole, combined with a dog orloop presenting parallel locking-arms having bent portions to enter saidbore or hole, and lock and draw the said plate and head firmly to theend of vthe-body, substantially as described.

3. A spool-body having a transverse bore or hole, a head andjournal-plate, combined with a dog or loop presenting' parallellocking-arms having bent portions to enter said bore or hole, said bentportions bein g provided with hooked ends to engage and lock togetherWhen driven into said bore or hole in the body, substantially asdescribed.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing Witnesses.
